Mold Botrytis Resistance

Botrytis cinerea, commonly known as gray mold, represents a significant cultivation challenge in cannabis production, particularly in humid environments. Plants exhibiting mold botrytis resistance typically display genetic or phenotypic traits that reduce susceptibility to fungal colonization—such as denser trichome production, modified leaf surface chemistry, or improved air circulation within the canopy structure. Lineage records frequently report that certain cultivars demonstrate lower infection rates under high-humidity conditions, though environmental management remains the primary control factor. This trait is not an aroma in the traditional sense but rather a plant characteristic sometimes associated with specific terpene profiles or morphological features. Breeders working in humid climates have prioritized selecting parent plants showing observable resistance markers. Understan

Breeders select for botrytis resistance by identifying parent plants that demonstrate reduced mold colonization in humid test environments and maintaining those genetics through controlled breeding programs. This trait is particularly valuable for outdoor and greenhouse operations in regions with high rainfall or persistent moisture conditions.
